Like numerals of reference indicate: corresponding parts in the various figures.

Referring to the drawings the barrel charring device shown in Figures 1, 2, 3, and 4 consists of the hollow or cylindrical body as indicated by the numeral l5. This cylindrical body I5 is open at both ends and made of aluminum or any other suitable material. The reinforcing angle I6 is welded or otherwise secured around the upper end of the cylindrical body 15, while the reinforcing angle I! is secured around the lower end of same. The cylindrical body I5 is suitably secured on the plate or base l8. This plate has the reinforcing angles I 9 welded or otherwise secured around the under side thereof. The plate is and reinforcing angles l9 form a base for the cylindrical body [5 and the barrel 2!].

The heating elements 2! are mounted on the cylindrical body i5 50 as to form a plurality of vertical heaters equally spaced around the cylindrical body. The support rings 22, 23 and 24 are made of steel or any other suitable material, and suitably secured on the outer surface of the cylindrical body l5. The heating elements 2| are secured to the support rings 22, 23 and 24 by means of the clips 25.

These heating elements are of a conventional type, having a conducting element which is insulated and contained in metal tubing.

The outer diameter of the support ring 22 is lar er than that of the support ring 23 and 24 thus holding the central portion of the heating elements 2| out further from the cylindrical body I 5 so as to follow the contour of the barrels which are placed over same. The upper and lower portion of the heating elements 2| enter the cylindrical body l5 through the clearance holes 27 in same.

The upper ring or bus bar 28 has a plurality of holes equally spaced in same which accommodates the upper end of the heating elements 2|. The ends of these heating elements are threaded and provided with nuts which secure the same substantially to the upper ring 28. The lower end of the heating elements 2| are secured to the lower ring or bus bar 29 in a similar manner to that in which the upper end of the heating elements are secured to the upper ring 28.

The upper ring 28 and the lower ring 29 are connected to an electrical power source by means of the cables 30 and 3 i' respectively. These cables are covered with asbestos insulation and extend downward from their respective rings through the hole 32 in the plate l8 and lead into the terminal box 33. From this terminal box to the power source the cables 30 and 3! are covered with ordinary insulation.

The charring device 34 shown in Figures 5, 6, 7 and 8 provides a means of charring the covers or ends for the barrels. This device consists of a frame 35 which has angle iron uprights 36 and braces 31 and 38 reinforcing same. This frame 35 forms a square base for the plate 40. This plate is made of aluminum or any other suitable material and welded or otherwise secured on the frame 35.

The heating elements 4| are mounted on the plate 45 so as to form a plurality of heaters equallyspaced apart and parallel to one another. The support bars 42 are made of steel or other suitable material, and suitably secured on the upper surface of the plate 40. The heating elements 2! are secured to the support bars 42 by 1 means of the clips 43. These heating-elements 4 l-' are U-shaped permitting the free ends .of same to extend downward through the clearance holes 45 in the plate 40.

The connecting bars 48 and' i'i have aplurality of holes in each which accommodate the free ends of the heating elements 4|. These free ends of theheating elements 4| are threaded and each areprovided with a pair ofnuts which secure same substantially to the bus bars 46 and 41. These connecting bars 48 and i? are connected to an electrical power source by means of the cables. 48 and 59 respectively. These cables are covered with asbestos insulation and extend fixedly secured to the lugs 55. The nuts 56 are threaded on these adjusting studs and providea means of raising and lowering the support 54 andbarrel cover 53. When these nuts 58 are tightened against the lugs 5| the barrel cover is raised, and when the nuts are loosened away from theselugs the barrel cover falls by means of gravity.

The charring devise is wired so as to guard against over-charring of the barrels and covers as well as to control the extent to which same will be charred.

In the wiring diagram shown in Figure 9 the incoming power line is indicated by-the numeral 7 This power line is connected to a power source, and in turn, is connected to the magnetic switch 58. The timer control 59 is connected to the magnetic switch 58 and provides a means of operating same. This timer controlis adapted to be set so that it will operate within a definite period of time, thus breaking contact with the power source. The magnetic switch 58 is connected to the transformer 50, which is adapted to step down the current to the proper voltage for operating the charring device. The transformer 58 is connected to the single throw switch 61 which provides a means of disconnecting the apparatus. The single throw switch 6 l 'is connected to the reversin magnetic switch 82 which, in turn, is connected to the thermostat 63. This thermostat 53 is inserted in the bung in the barrel and operates the relay 55 which in turn operates the reversing magnetic switch 62 thus controlling the charring of the barrel. The reversing magnetic switch 52 in co-opera- From this terminal reduces the current to a suitable voitage when stat 83.

the charring of the barrel 20 has reached a certain stage.

The thermostat 85 is suitably located a predetermined distance above the barrel 89. Thi thermostat 6B is set to operate in case the barrel should become ignited during the charring of same. In this case the temperature in the vicinity of the thermostat 68 would rise sufficiently to operate the latter. This thermostat 88 is connected to the magnetic switch 58 and controls the latter in case of emergency. The fire alarm bell 51 is connected to the magnetic switch 58 and is indirectly controlled by the thermostat 86.

The magnetic switch 68 is connected to the power line 51, and in turn, is connected to the timer control 69, the transformer 18, the single throw switch H, the reversing magnetic switch 12, the relay i3 and the thermostat M in the barrel 90. These electrical devices which control the charring of the barrel 8%! operate in a similar manner to that of the devices controlling the charring of the barrel 89.

Thethermostat 15-is suitably located a predetermined distance above the'barrel 98, and operates in case of emergency'in a similar manner to that of the thermostat 88.

The power line 5'! is connected to the magnetic switch 15. The timer control T! is connected to the'magnetic switch 16 and provides a means of operating same. This timer control is adapted tobe set so that it will operate within a-definite period of time, thus breaking contact with the power source. The magnetic switch 16 is connected to the transformer 19 which is adapted to step-down the current to the proper voltage for operating the charring device. The transformer 79 is connected to the double throw switch 80 which provides a means of either directing the current to'the device for charring the barrel Si or to the device for charring the barrel cover 92: This double throw switch 88 is connected to the reversing magnetic switches BI and 82 which, inturn, are connected to the thermostats 83 and! respectively. The thermostat 83 is inserted in the barrel 9i and operates in a similar manner to that of the thermostat 83.

The thermostat B l-is inserted between the cover 92 and the heating elements for same, and operates in a similar manner to that of the thermo- The relays 85 .and 85 areconnected to the reversing magnetic switches 8| and 82 'respectively .and are actually master of the latter. These reversing magnetic switches in co-operation with the relays 85 and 88 and the thermostats 83 and 84'respectively,.reduce the current to a suitable voltage when the charringof the barrel 9| or cover92 has reached a certain stage.

The thermostats 81 and 88 are suitably located apredetermined distanc above the: barrel 9| and barrel cover 92 respectively, and operate in case of emergency in a similap manner to that of the thermostat 66. a

In the operation of the barrel charrin device 33 shown in Figure 2 the barrel is .placed'over the heating elements of same-and-restson the base I8. The thermostat 53 "is inserted in the barrel 20 ready for user. Referring to-the wiring diagram shown in Figure 9 the barrels 88 ,90, and 9| are'prepared .for charring-in a similar manner. The electric current isswitched on and reduced to the desired voltage for charringthe barrels. 'When these barrels'beginto-char+the respective thermostats ineach barrel; in co-operatiorlwith the reversing-magnetic switches reduce the voltage permitting the completion of the charring to take place slowly. The timer controls connected to the electrical circuit for each of the barrels are set so as to break the circuit when same are charred to the desired degree. Should the barrels become ignited during the charring of same, the thermostats above each barrel are adapted to control the switches so as to break the electrical circuit and at the same time ring the firm alarm bell which is provided in case of such an emergency.

In the operation of the charring device for the barrel cover or barrel end 53 shown in Figure 6 the cover is placed over the heating elements of same and rests on the support 54. This support is adapted to be raised or lowered by means of the adjusting studs 52 so as to provide a suitable clearance between the cover 53 and the heating elements 4| of the device. Referring to the wiring diagram shown in Figure 9 the .barrel cover 60 is placed in position in a similar manner for charring. The electric current is switched on and the various controls operate in a similar manner to that of the controls for the barrels 89, 90 and 9!.

While three charring devices for barrels and one device for barrel covers are indicated in this instance, any number of devices may be employed at one time and suitably wired without generally affecting the advantages of the invention.

It will be seen from the foregoing that a means v.ior charring barrels and the like has been devised .that will assure the proper degree of charring, and at the same time, increase the exten to which barrels may be used in industry.
